Continued from page 1

120 MHz. Two clamps are provided with DB201 anten-

nas in the 30-120 MHz frequency range. Tighten the

mounting clamps securely and evenly. If two clamps

are used, ensure that the clamps are vertically aligned.

Using the supplied lockwashers and nuts, install the U-

bolts onto the base plate, leaving them loose enough

that the ground radials can be placed between the U-

bolts and the base plate. Slide the radials in until they

touch against the side of the adjacent U-bolt. Then,

tighten the U-bolts securely and evenly.

Mount the fully assembled antenna onto the tower en-

suring that the antenna is vertical and that the mount-

ing clamps are tightened evenly and securely.

It is recommended that a check of the antenna VSWR

is measured at this point. Note this measurement care-

fully and record it for future reference.

After checking the VSWR at the antenna, connect the

station transmission line to the antenna. Make the con-

nection snug, but do not apply heavy force with pliers.

To prevent moisture problems, carefully wrap VAPOR-

WRAP™ (11317 or 11316) around the connection; work

ing the compound into all cracks and smoothing it over

the outer jackets of the transmission line. Failure to wa-

terproof the cable connection will result in improper op-

eration of the antenna.

Secure the feeder cable and antenna transmission line

to the tower in the best position as to avoid physical

damage to the cable.

10. After the antenna and transmission line installation has

been completed, a careful visual check should be made

to ensure that:

•

All mechanical connections have been securely made.

•

All connections have been securely wrapped with

VAPOR-WRAP™ to prevent moisture problems.

The installation, maintenance, or removal of an antenna

requires qualified, experienced personnel. Andrew installation

instructions are written for such installation personnel.

Antenna systems should be inspected once a year by qualified

personnel to verify proper installation, maintenance, and

condition of equipment.

Andrew disclaims any liability or responsibility for the results

of improper or unsafe installation practices.
